Correction to: ADHD Attention Deficit and Hyperactivity Disorders https://doi.org/10.1007/s12402-018-0272-y

Authors have noted one error in the online published article, which they wish to clarify. The version of the Hobby Hyperfocus (HF) subscale that we administered to participants was unintentionally missing one answer option (“once a week”). Thus, the available answer options included:

  • Never

  • 1–2 times in 6 months

  • 1–2 times a month

  • (Missing “once a week”)

  • 2–3 times a week

  • Daily

This means that the total Hobby HF scores reported in the paper were scored out of 60 possible points, rather than the 72 possible points indicated in the paper. Participants may have responded differently to this scale due to the absence of this one answer option.

This mistake does not change any of the values or statistical analyses reported in the paper, as we reported total scores in each case. Further, as we identified significant associations between each of the HF subscales and ADHD symptomology, we did not directly compare Hobby HF scores to school or screen time HF scores. Thus, our interpretation of results and overall conclusions from the paper do not change.
